We also live in NE Wisconsin. This is a sad year for my garden. Green beans just started to blossom, but peppers & Tomatoes are in the same row and I have lots of tomatoes and early peppers on plants that are 6" tall & so are the peppers.
My peaches look bad, but pears are loaded. Pumpkins are just starting to bloom & small plants, it better not freeze till Christmas to get big pumpkins. Now all these garden items are next to my apple trees & grapes, and they are both loaded. so it can`t be lack ob bees, I think it was the long very hot days from May up to now. We had lots of rain, but some plants can`t take the heat.
